ABSTRACT
The aim of this study was to evaluate the edge effect using the macrofauna community of the
soil as indicator in three fragments of Semi-deciduous Seasonal Forest in the city of Vitória da
Conquista, Bahia, Brazil. Three sampling ranges denominated edge, transition and interior were
delimited in each fragment. The macrofauna community was sampled at two seasons of the year
(dry and wet). Monoliths were collected from soil at 10 cm depth in each range. The density and
richness of the fauna, as well as the Shannon diversity index and the Pielou equitability index,
were calculated. It was observed that the edge effect is expressed from the presence/absence of
orders of individuals in the different fragment ranges, with no interference in the density, average
wealth or number of individuals in each group. The edaphic community presents higher density
and average richness in the dry period within the transition and interior range of the fragments.
Keywords: fragmentation, density, richness.
